I'll share my dirty secret with you - if I'm really worn out during the day at work, I've done a 15 minute nap in my car. At some point I realize that I'm not being productive at all and would space out anyway at my desk, better to kill 15 minutes and come back refreshed. YMMV depending on your parking location. I park in underground parking that makes for a comfortable nap. Just make sure not to park in front of the elevator, haha.
